Add missing <cstdint> includes

Done with the following script:

```ruby
Dir["Source/**/*.{h,c,cc,cpp,hpp}"].each do |path|
  v = File.read(path)
  next if !v.include?("uint32_t") || v.include?("cstdint")

  lines = v.lines
  line_num = if lines[2].start_with?(" *")
    lines.index { |l| l.start_with?(" */") } + 3
  else
    3
  end

  lines.insert(line_num, "#include <cstdint>\n")

  File.write(path, lines.join(""))
end
```

then fixed-up manually
